MACHINE FOR STRAIGHTENING AND POLISHING IRON, STEEL, AND OTHER METAL RODS SPECIFICATION forming part of Letters Patent No.V 253,710, dated February 14, 1882.

Application filed September 13, 1881.

To all 'whom it may concern:

Be it known that I, JOHN ILLiNewoRTH, ot' the city of Newark, Essex county, in the State of New Jersey, have invented certain new and useful Improvements in Machinery for Polishing and Straightening Iron, Steel, and other Metal Rods, of which the following is a speciication.

In the drawings, Figure 1 is a plan View. Fig. 2 is a side elevation. Fig. 3 is a detail showing lateraladj ustment of main shaft. Fig. 4 is a detail showing` end adjustment of main shaft.

My invention relates to a simple, strong, and efficient construction of that class of rollingmachines in which revolving disks are used to straighten and polish rods of iron, steel, or other metal.

I am aware of the Letters Patent granted to Reese in 1867 and to Brooksbank iu 1874, and do not claim any features shown by them. l

A is the frame-work and foundation; B, the main shaft; C C', the disk-rolls; D, the shaft of roll C, and also carries its pinion D', which engages with small pinion E on independent shaft E. F is a driving-pinion on shaft B, and imparts motion to pinion E.

Disk-roll C has its independent shaft G and large pinion G', which engages with the main pinion H on main shaft B. The gearing is so arranged that the disk-rolls C C revolve with equal velocity in opposite directions-that is, their centers and peripheries do so revolve. Roll C has a plane face. Roll C has a conical face, so that its face of contact with the rod from center of disk to its periphery is longer than corresponding part of the face of roll C. From this it results that a forwardfeeding motion, in addition to the rotary motion, is imparted to the rod grasped between the two disk-rolls.

My construction, consisting of one conicalfaced disk operating in connection with one plane-faced disk, has important advantages over a machine having either two plane-faced disks or two conical-faced disks, and especially when, as in my machine, all of the shafting and gearing arein parallel lines, as shown (No model.)

in the drawings, the parallel arrangement securing steadier and better action. Experience in the use of such machinery has taught me that when two plane-faced disks are geared together in the manner shown by me the rods will be broken off in lengths equal to one-half the disk-diameter, so that the machine is practically useless unless another and inferior system of gearing is adopted. lI do not philosophize as to the cause of this peculiar action of the two plane disks-I merely state the fact. When two conical-faced disks are geared together the rod passing through has too much play and is liable to become bent and come out bent or crooked instead of straight; and the parallel system of gearing is not available. ln my machine the long (whole diameter) plane face of the one disk remains at all times in contact with the passing rod, affording a constant resistance from that side of the machine.`-` At the same time the conical disk, fronritscenter to its periphery, (that face of it which is parallel to the plane disk,) is holding the rod against the plane disk by a parallel pressure, thus securing the rod in such a way that it shall pass out ofthe machine in a straight line and in a straight form. I prefer a low cone, j ust conical enough to readily admit entry Yof rods between the two disks.

By means of wedges operated in wedge-boxes by set-screws, proper end and lateral adjustment is given to the disk-roll C. This is fully shown in Figs. 3 and 4, in which G is the shaft of roll G/and revolves in journalboxes I, housed in the standards A. Abutting against opposite sides of boxes I are the adjustableV wedges L, which play up and down by means of set-screws S in the wedgeboxes W, so as to secure a lateral adjustment of shaft G, and thus secure the desired angle at which roll C shall revolve with relation to roll C.

In Fig. 4 is shown the device of securing en'd adjustment of shaft G and its disk-roll C', according to the thickness of the rod to be rolled. In this case wedges O are operated in wedge-boxes O by set-screws I against a co1- lar, V, on shaft G. As the wedges are raised by the screws the collar and its shaft G and disk C are forced outward toward disk C. The combination, with the plane-faced disk These Inodesof securing lateral and end ad- C, of the conical-faced disk C', arranged as justment are exact, strong, and simple. and for the purpose set forth.
